Hi Vint,
Keeping the final motive of doing a volume copy aside.
What we are trying is to creat a new Vdisk, my assumption is that you have two controller in MSA.
Try following and confirm the status :--
a) Try creating Vdisk using other controller IP, that is if we have used controller A IP earlier and have attempted with the error, then try opening SMU using controller B IP.
b) Restart the management controller (MC) of both controller ( restart mc both ) and then try creating the Vdisk using any other Vdisk name ( apart from Vd2 ).
Confirm the status following that....
